hi.thanks for replying.
there was 3 partitions i believe in "my computer",C,vista or toshiba(as i recall). and a 3th one "BOOT".
I can't get to them obviously as i can't start windows,but if i try "complete pc restore" at the repair wizard,it gives me the option to look for a "system file",but where to find it for god sakes!!
sfc /scannow in the command promp did not work..
